Question 388664
If we let a = number of adults and c = number of children, then the total daily cost for 'a' adults is {{{15a}}} and the total daily cost for 'c' children is {{{5c}}}



Add these up to get {{{15a+5c}}}. So the total daily cost is {{{15a+5c}}}



If your hypothetical family has 1 adult and 2 children, then {{{a=1}}} and {{{c=2}}} meaning that the total daily cost is {{{15(1)+5(2)=15+10=25}}}



If they plan to visit 24 times a year, this means that the yearly cost is then {{{24*25=600}}} dollars



So in this case, it's definitely cheaper to buy the $80 annual membership.
